Archer (EMIYA) [Fate/Stay Night] - He's been through several wars, battlefields, etc. as a Counter Guardian. He's skilled in Archery and is good with swords, him being trained by Saber and all in his past life. He's picked up battle experience worth a hundred lifetimes. Could spam swords if not for the OP's restriction.

Kawakami Momoyo [Maji de Watashi ni Koishinasai!] - She's the brawler and speed fighter. Can regenerate wounds, which may or may not make her fully immune to zombies. Did I also mention that (in the one of the VN's sequel) she can fight in space?

No powers but still skilled even without it. Vash and Train balances out Grave's quiet nature. Never gets boring, All 3 are good at survival on the streets and beyond. I think we can make through it alright.

What happens when they run out of ammo?

Brandon Heat - Trained in CQC with a preferred weapon for metal pipes or other blunt objects thanks to his childhood.

Vash the Stampede - Trained in CQC thanks to living on his own in the harsh world of gunsmoke nearly all his life.
Me - Hide behind them as always,giving them cheers.

Kyon - His cynisism would depress all the the zombies so much that they'd just leave.
Touma - He could just poke the zombies with his right hand and they die (Assuming that they're some kind of supernatural phenomenom.)
Izayoi (Problem Children) - Because he's just a badass.
Aikawa Ayumu - STEALTH OPERATIONS!
Nyaruko - I'm pretty sure Aliens > Zombies.
